The son of the late German zookeeper who cared for Knut the polar bear is selling his father's possessions on eBay.

Thomas Doerflein, who worked at the Berlin Zoo and was known as the famous cub's surrogate father, died at 44 of a heart attack in September. The sale of his belongings has brought in 7,000 euros ($9,748) so far, and includes the sleeping bag Doerflein used while caring for Knut round the clock and his 10-year-old car. Doerflein's former fiance condemned the sale as "tasteless." His 18-year-old son reportedly needed money to buy his father's tombstone and care for his grave. [Reuters]
